Jeffrey Dietrich is a bioengineer-turned-coffee-founder who built Rarebird around paraxanthine, the molecule your body actually makes when it metabolizes caffeine. After a PhD at UC Berkeley in Jay Keasling's lab and nearly a decade co-founding and running R&D at the industrial biotech company Lygos, Dietrich turned his own dwindling caffeine tolerance into a company. Rarebird sells decaffeinated specialty coffee infused with lab-grade paraxanthine, promising the lift of coffee without the jitters, crash, or ruined sleep. Backed by Y Combinator, AgFunder, and two NSF grants, the company holds U.S. patents on the process and won the Specialty Coffee Association's Best New Product award.
Rosa Li is the founder and CEO of wildwonder, the sparkling beverage brand she built around the herbal tonics her grandmother brewed in Beijing. A Stanford MBA and former private equity investor, she traded Wall Street spreadsheets for a homemade carbonation rig made from a beer keg, launched in 2020, and landed a deal with DoorDash CEO Tony Xu on Shark Tank in 2023. wildwonder now reaches 3,000-plus retailers across 40 states and has sold millions of cans.
David Lester is the co-founder and former President of OLIPOP PBC, the prebiotic soda brand that grew from a $100,000 bet into a $1.85 billion company in under seven years. A former Diageo brand marketer who worked with Smirnoff, Gordon's Gin, and Johnnie Walker across three continents, Lester paired his CPG expertise with co-founder Ben Goodwin's scientific formulation genius to create a soda that supports gut health without sacrificing the nostalgia of a cold fizzy drink. OLIPOP now generates over $425 million in annual revenue, holds 65,000+ retail doors, and controls 87% of the functional soda category - a category it essentially invented.
